blade suborbiculate to reniform, 3- or 5-lobed, cleft 1/4–1/3 to midrib, (1–)2.6–6.5(–8.5) cm, base deeply cordate, surfaces sparsely stipitate-glandular (otherwise nearly glabrous) to downy along veins, copiously soft-pubescent and glandular, lobes rounded, margins irregularly 1 or 2 times coarsely crenate-dentate, apex rounded to broadly acute.

petiole 1–3 cm, pilose with glandular and eglandular hairs, some plumose hairs at base;

blade roundish to nearly reniform, 3- (or 5-)lobed, cleft 1/2 to midrib, proximal segments again shallowly cleft into 2 unequal lobes, 2–3.5 cm, base rounded to cordate, surfaces pubescent abaxially, subglabrous or finely pubescent adaxially, lobes cuneate, margins prominently crenate-serrate, apex rounded.

erect to somewhat pendent, (3–)6–17-flowered racemes, 3–10 cm (shorter than leaves), axis copiously pubescent and stipitate-glandular, flowers clustered at end of peduncle.

pendent, solitary flowers or 2–4-flowered racemes, 2–4 cm, axis glabrous or pilose, flowers evenly spaced.

jointed, (2.7–)3.5–10(–12) mm, pubescent, stipitate-glandular;

bracts lanceolate to oblanceolate, (5–)6–8.5(–12) mm, stipitate-glandular.

not jointed, 3–12 mm, glabrous or pilose;

bracts oval, 1–2 mm, glabrous or ciliate with stiff hairs and glands.

hypanthium greenish, greenish yellow, or yellowish white, sometimes strongly pinkish or purplish tinged, campanulate to tubular-campanulate, (4.5–)7–8 mm, sparsely to densely hairy and stipitate-glandular abaxially, glabrous adaxially;

sepals not overlapping, spreading at anthesis, becoming erect, whitish green, sometimes tinged with pink or purple, lanceolate-elliptic, (3.5–)4–7 mm;

petals connivent, erect, white or cream, obovate-spatulate, not conspicuously revolute or inrolled, 2.5–4 mm;

nectary disc not prominent;

stamens 2.5–3.5 times as long as petals;

filaments linear, 3.5–7 mm, glabrous;

anthers cream, oval, 1 mm, apex rounded;

ovary glabrous;
